TO ALL WHOM IT MAY CONCERN:

Be it known that I, DAVID B. GOEWEY, of Birmingham, in county of Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in Mortising Spokes in the Hubs ofA Wheels, Rounds in Chairs, dta; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and the letters of reference marked thereon.

My invention consists in making the tenon corrugated or curved, so that the convexed or gibbous portion of the tenonwill be of greater size than the mortise in which it is to be driven. My invention in connection with said corrugated or curved tenon further consists in making the part in which the mortise is formed pliable by means of steam, Water, or by other suitable means; the tenon and its mortise being constructed, arranged, and operating in the manner hereinafter describedA To enable others skilled in the art to make and use m'yinvention, I will proceed to describe its construction and operation. In the accompanying drawings, Whichform part of my specification- Figure I represents a transverse section of a hub ot' a Wagon-Wheel showing the form of the tenon andV mortise, when the spokes are secured in the hub of a Wheel by my improvement.

Figure represents a central section of a tenon and its mortise when/the tenon and mortise are round.

I make the mcrtise in any of the known forms, and by any of the known means. I make the tenon by any known means, and in size to correspond to the mortise, taking care, however, to have it corrugated or gibbous, which corrugated or gibbous portion ot' the tenon must be of greater size than its mortise, as shown in fig. I, by the lines X and J. In the accompanying drawings- A represents the huh of a wagon-Wheel; B represents the spokes; e represents the forni of the mortise and tenon after the spokes are secured in the Wheel; C represents the form of the mcrtise prior to receiving the tenon D. Before driving the tenon into the mortise, I steam or soak the mortised part in water until the mortised portion becomes pliable so that the mortise will yield to the form of the tenon without splitting. Glue, cement,

or other adhesive matter may be applied to the tenon. and mortise in the usual manner, and the tenon forced into the mortise by any known means. The hubs of' Wagonwheels should be provided with iron bands, and the mortises formed in the hub prior to steaming or soaking the hub in`water. 'Ihe advantage of my improvement, when used for mortising doors, shutters, sash, stair balusters, rounds in chairs, handles in mallets, spokes in the hubs oi' wheels, or any other Athing in which a tenon and mortise can be used, will be very apparent to the skillful mechanic without further description.

I wish it clearly understood that I do not claim broadly a corrugated or gibbous tenon, for such is used in the manufacturing of chairs, hand-rakes, the., but what I do claim, is

Corrugating the tenons of spokes of wheels, and bracing and uniting the ends ot' said tenons in their mortise so asto form a solid part of hub, as heroin described and for thepurpose set forth.
